    • A method and composition for reducing or eliminating stinging that may accompany application of topical solution of a skin-compatible polymeric material to a skin wound, abrasion, burn or other skin injury. The topical solution may contain one or more skin-irritating chemicals, such as diethyl ether, ethanol, ethyl acetate, methyl acetate, acetone, methyl ethyl ketone and combinations thereof. The method includes: (i) providing a composition that contains between 1% and 10% by weight of the skin-compatible polymeric material dissolved in a liquid medium suitable for human topical use in which the liquid medium includes less than 20% combined weight of skin-irritating chemicals, and at least 45% combined weight of at least one volatile solvent and/or volatile co-solvent, in which the molecules constituting this 45% combined weight portion of the liquid medium contain at least 5 carbon atoms, and the liquid medium has an initial boiling point at 1 atmosphere of greater than 35°C and less than 150°C, and causes little or no stinging when applied to a skin injury, and (ii) applying the composition to the skin of a patient at the site of the skin injury.
    • 用于减少或消除可能伴随皮肤相容性聚合物材料的局部溶液应用于皮肤伤口,磨损,灼伤或其他皮肤损伤的刺痛的方法和组合物。 局部溶液可含有一种或多种皮肤刺激性化学物质,如乙醚,乙醇,乙酸乙酯,乙酸甲酯,丙酮,甲乙酮及其组合。 该方法包括:(i)提供一种组合物,其含有溶解在适用于人体局部应用的液体介质中的1重量%至10重量%的所述皮肤相容性聚合物材料,其中所述液体介质包含小于20重量% 刺激皮肤的化学物质和至少45%的组合重量的至少一种挥发性溶剂和/或挥发性共溶剂,其中构成该液体介质的45重量%组合重量部分的分子含有至少5个碳原子,并且 液体培养基在1个大气压下的初始沸点大于35℃且小于150℃,并且当施用于皮肤损伤时引起很少或没有刺痛,和(ii)将所述组合物施用于患者的皮肤上 皮肤损伤的部位。
